Global Event Series: Watch Your Waste Meals


Image title


Join us in this global effort — host a Watch Your Waste Meal in your community!

Food is a core part of the human experience, yet annually we waste a third of all of the food produced worldwide. That’s why we’re kicking off our Food Waste Challenge, tackling this question:  

How might we dramatically reduce waste by transforming our relationship with food?

With every design thinking Challenge, we start with empathy. Our Research phase is mobilizing 100,000+ people in our global community to collect powerful stories, examples, and insights about food waste worldwide to help us understand the core of the issue.

We’ve heard so far that an obstacle to addressing waste is that many people aren’t aware of the food they’re tossing away. To address this, we’re launching #Unwasted, a series of collaborative efforts that highlight the food we throw out every day. We’re kicking off #Unwasted with a global event series called Watch Your Waste Meals.  


Hosting a Watch Your Waste Meal is simple:

Invite your friends and family to share a meal together and discuss how food waste shows up in your lives. In the week leading up to your event, we’ll encourage you to track your food waste using a diary that we’ve included in our event toolkit.

After the meal, you’ll submit a contribution to the Watch Your Waste Meals Mission on the Research Phase of the Food Waste Challenge. This will be an opportunity to share your experience with our global community. You won't want to miss this: a few contributors will be featured in our Unwasted pop-up magazine, and may be selected to have their scraps turned into a signature dish by one of our celebrity chefs in our upcoming Unwasted Cookoff!

Our goal is to have 100 meals planned across 20 countries during the week of August 5 – August 15. Whether you bring four friends to your living room for a potluck or host a larger dinner at a community space, this is an opportunity to catalyze conversations about this important topic.


Here's a step-by-step guide to host your Watch Your Waste Meal:

  • Complete this form to tell us about your event, and we will include it on our list below.
  • Invite friends and family.
  • We’ve created a Watch Your Waste Meal Toolkita step-by-step guide to help you organize a successful event, plan a meal with food waste in mind, and facilitate an interesting conversation.
  • Track your waste in the days leading up to your event using our Food Waste Diary (don't skip this step if you want to get your food scraps #unwasted by a celebrity chef)!
  • The organizer and at least one participant should post contributions & their completed Food Waste Diaries on the Watch Your Waste Meal Mission in the Food Waste Challenge before August 16.
  • The best contributions will be selected to be published on our #Unwasted pop-up magazine on Medium.
  • Share photos and multimedia from your events with the #Unwasted hashtag (and don't forget to tag @OpenIDEO)
    • Take a picture & tweet/email/facebook message us a quick list of the food scraps left over from your Meal for your chance to enter your scraps into the Unwasted Cookoff (more details coming soon)!
